1099 Contractor in New Jersey with a Alabama Client: Where Do You File?
Answer
The client's location does not decide this. Self-employment income from personal services is sourced to where the work happens, so working from New Jersey keeps it New Jersey-source and New Jersey-taxed. Travel to Alabama to work and that portion becomes Alabama-source, needing a Alabama nonresident return.

The client's location is the wrong thing to track. What matters is where you were sitting when you did the work — which is why a contractor's exposure to Alabama is measured in days on the ground rather than in invoices sent.
Alabama publishes no de minimis day count or dollar floor for nonresidents. Any Alabama-source wage income above the state's general filing threshold requires a nonresident return, and that threshold is reset each year — check the current figure on the Alabama Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in New Jersey and my client is in Alabama. Do I have to file a Alabama tax return?
The client's location does not decide this. Self-employment income from personal services is sourced to where the work happens, so working from New Jersey keeps it New Jersey-source and New Jersey-taxed. Travel to Alabama to work and that portion becomes Alabama-source, needing a Alabama nonresident return.
Do reciprocity agreements help a 1099 contractor?
No. Every state reciprocity agreement in the country is an arrangement about wage withholding between two revenue departments, and a 1099 has no withholding to switch off. Whether New Jersey and Alabama hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
